Michael Irwin, who has served as CFO of Webroot since September 2004, will assume the role of chief operating officer (COO).

The addition of Pace comes as Webroot closed out the most successful quarter in the company's history on December 31.

"As we move forward in 2006, we are expanding our operations both globally and domestically to continue our strong growth pattern," said David Moll, CEO of Webroot."

He also served as CFO of M2 Networx, a provider of desktop collaboration services, and he was the vice president of financial planning & analysis for Covad Communications.

"Webroot has hit a very exciting stage in the corporate lifecycle and is well positioned for increasing financial success on a global scale," said Pace. "The company is the technology leader in a rapidly expanding global market, and as CFO I plan to leverage Webroot's success to increase the trajectory of financial performance."

Prior to Covad, Pace spent eight years with US WEST Communications. Before his departure, he served as executive director of finance for the Designed Services unit that delivered telephony and data products to 14 states and 16 million users. He began his career at Deloitte & Touche as a senior auditor.

As part of Webroot's executive expansion, Irwin will move from CFO to the role of COO. In this new position, Irwin will be responsible for overseeing all internal operations of Webroot, in addition to strategically driving forward the overall business and company objectives.

"Mike's management and leadership abilities have strongly aided Webroot in achieving record financial success and solidifying the company's top market position," said Moll. "As we move into 2006, Mike will be leading our operational efforts to expand the company's global reach and technology excellence."
